-LRB- CNN -RRB- -- Antonio Margarito has apologized for mocking Manny Pacquiao 's Parkinson 's disease-afflicted boxing trainer Freddie Roach in a video that has spread like wildfire across the Internet .

The Mexican-American boxer made a surprise appearance at Thursday 's press conference for the undercard bout between Brandon Rios -- who was also in the video -- and Omri Rowther in a bid to make peace ahead of Saturday 's fight in Arlington , Texas .

`` I want to apologize to everyone , Freddie Roach if he will accept my apologies , '' said Margarito , who was filmed shaking his hands in mock horror when a journalist told him Roach said Pacquiao would win by a knockout .

`` To everyone with that disease ... I want to tell you , never , ever in my life would I make fun of anyone like that . I just want to let you know that I 'm not the kind of person who would do anything like that , and make fun of anyone . ''

Rios also said sorry to the 50-year-old for his part in the viral clip , which was posted on video sharing website YouTube on Wednesday and showed the American boxer violently shaking his head and stammering .

`` It was a bad video from my behalf . Things got heated up in the moment . And I 'm sorry . I feel bad for saying it . Nothing personal . I feel bad , '' he said .

Robert Garcia , who trains both Maragarito and Rios , told reporters at the conference that he had spoken to Roach and his opposite number had accepted the apology .

`` I told him , ` Freddie Roach , I want to tell you that I 'm very sorry for what happened . Now that I am talking to you , I feel much better , ' '' Garcia said , adding that Roach replied : `` I accept your apology . And best of luck this weekend . ''

Roach said he had been angry about the video , but was prepared to move on , the Sweet Science boxing site reported on Thursday .

`` I wanted to fight them at first , of course I 'm a little too old , '' he said . `` I was very upset at first , I had trouble sleeping , thinking what to do about it . I thought it 's best to take the high road , chalk it up to experience .

`` They made a mistake , went too far -- but I think they should apologize to world and not just me . They went a little bit too far , tried to get under my skin but they 're attacking a group of people -- not just me has Parkinson 's .

`` They apologized , they made a mistake , I accept it , let 's get to the fight . I will not let it get to me or my fighter -- my fighter is smart and will stick to the game plan . They went a little bit too far , but we can all do that at times . I do n't think they meant any harm in it . ''

Pacquiao and Margarito are fighting for the vacant WBC junior middleweight title at Cowboys Stadium , with Filipino fighter seeking to claim a belt in an unprecedented eighth class .

It is Pacquiao 's second visit to the venue , having retained his WBO welterweight title there against Nigeria 's Joshua Clottey in March .

Margarito comes into the fight with a record of 38 wins from 45 bouts , having won both the WBO and IBF welterweight titles .

However , the 32-year-old was mired in controversy after he was found to have used illegal handwraps during his WBA title defeat by Shane Mosley in January 2009 , leading to him being banned by the California State Athletic Commission .

He returned in May to win the vacant WBC International light middleweight title from Roberto Garcia before being signed up by promoter Bob Arum , with Pacquiao still unable to seal a deal for his dream clash with Floyd Mayweather Junior .
